This project will conceptually design and demonstrate the feasibility of a multivariate approach to the real-time measurement of cognitive workload, basedon operator psychophysiology as well as behavior, in the context of task demands. Such as approach will facilitate the development of cooperative human-computer controversy over how to implement such capabilities, including how to ascertain the ...

This project involves research and development of a means for reusing existing digital models and test vectors generated using the LASAR and HITS ATPG for digital test programs that are currently hosted on absolete and non-supported automatic test equipment. The approach identified herein promotes translation of LASAR and HITS ATPG into VXIbus-compatible instrument functions that are interoperabl ...

An ultrasonic Rayleigh surface wave method is propose to determine residual stress depth profile in aluminum aircraft wheels. The Rayleigh wave method has several distinct advantages. The residual stress depth profile can be easily obtained by altering the penetration depth of the Rayleigh wave. The Rayleigh wave is bound to the surface of the wheel, enabling measurements on curved and ...

An ultrasonic method is proposed to determine the level of pre-tension in rails of the high speed test-track. The specific ultrasonic approach has the benefits of being able to perform measurements without the need to account for the texture in the sample and can be used on structures with irregular geometries. The ultrasonic technique can also be used to establish the temperature dependent chan ...

To field characterize laser systems the laser power, beam divergence, intensity profile and spot size of the laser must be measured with a robust, vibration insensitive system. While some of these parameters can be obtained using conventional components, beam divergence is difficult to measure because of the complexity and vibration sensitivity of typical interferometry based elements. We propos ...

The world around us is three dimensional (3D), yet most existing cameras and display systems handle only two dimensional (2D) flat images that lack the depth information. This fundamental restriction greatly limits the capability of human being in perceiving and understanding the complexity of real world objects.One common problem shared by past development efforts of a number of 3D volumetric di ...

This project will develop a method for forming and emplacing a horizontal barrier within a groundwater aquifer to prevent downward migration and further contamination of groundwaters by Non-Aqueous Phase Liquids (NAPLs). Certain properties of the immiscible liquid system act to form the barrier from injected particulate or colloidal materials and to stabilize the barrier once it is form ...

Both catalysis and corona discharge are known to be separately capable of effecting the oxidation of NO to NO2 or higher. However, both have shortcomings in practical application: The power required for high efficiency NO oxidation using corona can be excessive, and most catalysts require high temperature to be effective and they are capable of oxidizing NO only to the NO2 level which ...
